METHUD 03? NAME AUTQEEQ'lEELlE-TI Patented at" '23 Application mea mains, mac. semi Ho. acacia To all whom it may concern:

Be it known that LJOEN H. Pii'i rnN, a citizen of the United States, and residin at Kent, in the county of King and State 0 Washin on, have invented certain new and useful mproveinents in Methods of Making Automobile-Tires, of which the following is a specification.-

This invention relates to automobile tires.

An object of the invention is to providea cord tire of durable construction, particularly the side walls which are subreat strains when turning curves, making 5 ort stops and the like.

,The invention also comprehends improvements in the method of making the tire, which will be hereinafter more particularly pointed out in the specification and claim.

In the drawings:

Figure 1 shows. tire on a form.

Fig. 2 shows a plan view of the cord layers in their relative positions.

1 indicates the form on which the tire is formed which is of usual construction. layer of ruhber 2 is first applied to the form, then a layer of cord 3 is wound biasly around the form over the layer of rubber, and a la 'er of cushion gum 4 15 applied over the cord layer. Beads 5 are then placed near the inner edges of the form and the a sectional view of-the 'cord layer is cut as indicated at 6, the ends being turned. outwardly and back a,ainst the side wall otthe tire to hold the lieads. by a thin coating of gum.

Another layer of around the periphery cord 7 is Wrapped of the tire and over the layer of gum 4 at an angle with the previous layer and covered with a coating of cushion gum 8. Another wrapping; of cord 9 is wound biasly on-the tire at an angle with the layer 7. The layers 7 and 9 are cut as indicated at 6 and bent inwardly around the beads and against the inner portions of the side walls and a thin coating of rubber applied to hold the ends fast.

secured ti The chafin strip 10 is next applied and tly around the inner edges of the tire, w ich is then covered with a layer of cushion gumfi.

'A covering 10 is now applied over the last layer 9* so that the edges extend to the inner edges of the tire as shown in Fig. 1.

This last coverlng m ris preferably of a different constituency and finishes the side walls of the tire, the tread l1 lasing ap piled over the covering 10 and the whole tire finally vulcanized to firmly unite the several layers The cord layers hein wound biaslv at a small'angle with t e transverse plane of the tire as shown in Fig; 2 and having; the ends wound around the heads as shown forms aconstruction which will withstand the heavy strains when starting, stopping orlur'ning corners. in starting and stopplug, the portion at a, Fig. 2 which is over the tread portion engaging with the ground receives the initial strain and exerts a force on the portions of the cords between a and b or a and 0, depending upon the direction of movement of the tire. This force pulls on the ends around the heads, the ends of the outer layer lockin the ends of the inner layer against the and preventing them from being pulled loose, and the angle of the cords gives the proper position so the have their maximum holding power.

l 'hat I claim is; r

A. method of making a cord tire consisting in coating a form with a layer of re silient material winding a layer of cord biasly over the resilient material applying a coat Poi cushion gum over the cord layer, applying beads. severing the cord layer on the inner periphery between the beads, bending the ends outwardly around is at the the beads and against the side we tire, winding a second layer of cord around the periphery of the construction thus made, applying layer of cushion gum over portions coatin r the tire with a layer of cushion mini ice over the last cord layer, coatin the tire with a layer ol resilient materia over the last mentioned chafing strips. and applying a layer of resilient. material over the last mentioned layer to form the tread.

In testimony whereofl atiix my signature in the presence of two witnesses.
